Application filed January 2,1923. Serial N10; 610,269.

1 '0 all whom it may concern:

Be it known that we, BALILLA VIENNA and Srnvro Grinsnrrn I FAVRETTI, both subjects of the King of Italy, and residents 5 of 252 Corso- Francia, Turin, in the Kingdom of Italy, have invented certain new and useful Improvements in Packing Cases or Boxes; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to a packing case or box provided with fastening and reinforcing means which improve its resistance and strength without increasing the weight beyond certain very narrow limits and re duce the size of the case or box.

According to this invention the side edges of the box are reinforced by means of angle bars which fit by their ends folded successively at right angles between the contact surfaces of a straight dovetail joint.

The nails are fitted in through the boards and the interposed metal bars, securing the whole in a permanent and solid way, which allows of the reinforcing cross bars to be dispensed with.

The transverse boards forming the cover are connected together by means of metal bands arranged in the wood in correspondence with the board heads. The band ends are folded under the end boards and the whole is secured to the case sides by nails passing through the wood and metal.

This arrangement prevents any partial opening of the case by fraud as in order to lift one of the boards it is necessary to break the metal bands connecting it to the others, which action is easily detected.

The accompanying drawings showa constructional form of this invention.

Figure 1 shows the reinforced edge of the case.

Figure 2 is a detail of the reinforcing angle bar.

Figure 3 is a section on line X-Y of Fig 4 showing how the bottom of the box is assembled.

Figure 4: is a section on line WZ of 55 Figure 3.

Referring to the drawings, A, B denote two contiguous walls of the box disposed at right angles and a, 6 denote the tenons for assembling the walls by means of a straight dovetail joint. The reinforcing element consists of a metal band having its two ends 1 and 2, respectively, folded at right angles.

The metal band is introduced from the inside so as to dispose its end 1 between the tenon a of the board A and the corresponding recess on the board B, and its end 2 between the tenon b on the board B and the bottom of the corresponding recess on the board A. 7

The ends of the reinforcing bar are out according to a mean line in order to fold them in the manner clearly illustrated, i. e. to superpose the ends 3 and 4 above and the ends 3" and 4. underneath on the boards A and B.

The case is then fastened with the nails 5 passing through the ends land 2 of the reinforcing element, as clearly shown. Smaller nails can conveniently be provided at the ends 3, 4 and 3', 4: of the bar. The walls A, B of the case can be made of several boards instead of being obtained in a single piece as shown in the drawing, without affecting the strength and usefulness of 8 the arrangement.

As mentioned above, the reinforcing bars can be provided with several elements similar to the one described (obtained from a single piece) for cases or boxes of a larger size and provided with several straight dovetail joints for each wall.

In case of splitting of the boards A, B the metal reinforcement will keep the parts assembled to ether preventing the case from being (1351185 to pieces.

The method of securing the cover and the bottom to the sides A, B is shown in Figures 3 and 4, in which 10 denotes the Wooden boards forming the bottom and cover to be 1 secured to the sides A, B mentioned above. The ends of the wooden boards 6 are provided with cuttings for introducing the metal band 7 which connects in correspondence with both ends all the wooden boards 6 forming the cover and the bottom of the case respectively.

The ends 7 of the bands 7 are folded under the cover (or bottom) and fit between same and the case headings A. The nails 8 for fastening the cover (or the bottom, respectively) to the sides B of the case pass through the bands A ensuring a strong connection of the Wooden boards 6. The bar further prevents lengthwise displacement of the boards.

What We claim is: I A packing case characterized by fastening and reinforcing means consisting of metal bars comprising elements having their ends folded at right angles and which on assembling the case fit between the contact surfaces of the straight dovetail joints of the boards and are traversed by nails, the ends of the said metal bars being folded and secured under the boards, and consisting further of bands lodged in cuttings on the-headings of the bottom (or cover) boards and strongly connecting together the said boards, the metal bands being traversed by nails and their ends being folded and secured between the bottom (or cover) and the box headings.

In testimony that We claim the foregoing as our invention, We have signed our names.
